Enabling PHP with NGINX

Based in part on this tutorial for a full "LEMP" stack -- this is just PHP for NGINX without MYSQL.

   sudo apt install php-fpm

if necessary...

   sudo apt install nginx

Then in nginx, the default settings has a template for enabling php, you just need to uncomment it (but leave one of the lines still commented out)... Here's the "final" settings

   sudo nano /etc/nginx/sites-available/default
